1. Understanding Frontier Airlines’ Pet Policy

Under the official Frontier Airlines’ pet policy, passengers can travel with small domesticated dogs, cats, rabbits, guinea pigs, hamsters, or small household birds in the cabin on most routes within the U.S. and Puerto Rico. However, pets are not accepted as checked baggage or in cargo holds, ensuring safety and better in-flight conditions.

Key Highlights of the Policy:

• Pets allowed in cabin: Dogs, cats, rabbits, guinea pigs, hamsters, and small birds.

• Maximum pets per passenger: One pet container per passenger.

• Pet age requirement: Minimum 8 weeks old.

• Pet health: Animals must be clean, odor-free, and non-aggressive.

If you have questions about your specific pet’s eligibility, call +1 (866) 558-3017 to speak to a Frontier representative directly.

2. Approved Pet Carrier Dimensions and Requirements

When traveling under the Frontier Airlines’ pet travel policy, your carrier must fit under the seat in front of you. Proper carrier selection is essential for your pet’s comfort and compliance.

Carrier Size Limit:

• Maximum dimensions: 18" length x 14" width x 8" height (45.7 cm x 35.5 cm x 20.3 cm)

• Type: Soft-sided carriers recommended for flexibility and comfort

Your pet must remain in the carrier throughout the flight — including takeoff, taxi, and landing. You can Book Now and verify your pet’s carrier specifications with Frontier’s team at +1 (866) 558-3017 before your trip.

3. Frontier Airlines Pet Fees (2025 Update)

Flying with your pet requires a small additional fee, but Frontier remains one of the most affordable airlines for pet owners.

Pet-in-Cabin Fee:

• $99 each way per pet container

Fees can be paid at booking or check-in. Travelers are encouraged to reserve pet spots early, as Frontier allows only a limited number of pets per flight.

4. Frontier Airlines’ International Pet Policy

Frontier’s international routes have more restrictions. While Frontier Airlines’ pet policy allows pets in the cabin on U.S. domestic flights, many international destinations prohibit animal entry.

For instance:

• Flights to/from Mexico and the Dominican Republic: Pets not accepted.

• Flights to Puerto Rico: Allowed, but specific vaccination and health certificate rules apply.

Always verify international rules directly with the airline by calling +1 (866) 558-3017 before booking.

5. Required Pet Documents and Health Certificates

The Frontier Airlines pet travel policy requires minimal documentation for domestic travel. However, proof of vaccination and age verification may be requested at any time.

For international or Puerto Rico flights, you must present:

• A valid health certificate issued within 10 days of travel.

• Rabies vaccination records.

• Import/export documentation (if applicable).

It’s always smart to double-check documentation rules with +1 (866) 558-3017 to ensure a smooth check-in process.

6. Boarding and In-Flight Guidelines for Pets

Traveling with pets doesn’t need to be stressful. The Frontier Airlines’ pet policy focuses on keeping both you and your animal comfortable during the flight.

Key boarding guidelines include:

• Check in at least 90 minutes before departure.

• Declare your pet at the check-in counter.

• Keep your pet in its carrier throughout the flight.

• The carrier counts as your personal item (no additional bag allowed).

7. Service Animals and Emotional Support Pets

Frontier follows U.S. Department of Transportation (DOT) regulations regarding service animals. Only trained service dogs are recognized under the Frontier Airlines’ pet travel policy in 2025.

Important Points:

• Emotional Support Animals (ESAs) are no longer considered service animals.

• Service dogs must be trained to assist passengers with disabilities.

• Required documentation must be provided before departure.

Contact +1 (866) 558-3017 to confirm eligibility and document submission guidelines before your flight.

8. Traveling with Multiple Pets

Under Frontier Airlines’ pet policy, only one pet container is permitted per passenger. Each container can hold up to two small animals of the same species, provided they fit comfortably and safely.

Example:

• Two small kittens can share a carrier if they can stand, turn, and lie down naturally.

If you plan to bring more than one pet, multiple travelers may need to make separate bookings. For details and coordination, reach out to +1 (866) 558-3017.

9. Tips to Make Pet Travel Easier (and Stress-Free)
